Deploying a cloud

The following is an idea/attempt to deploy an cloud.

Since aap is still in beta, this illustrates a desired yet incomplete workflow

Usecase

$ git clone https://github.com/username/my.aap.git && cd my.aap
$ aap install
Rebuilding docker 'mysql'
Rebuilding docker 'mongodb'
Rebuilding docker 'apache'
$ aap start 
Starting docker core-api    on 'https://coreapi.foobar.com' => 'http://0.0.0.0:3454'
Starting docker crm-api     on 'https://crm.foobar.com'     => 'http://0.0.0.0:3455'
Starting docker landingpage on 'https://www.foobar.com'     => 'http://0.0.0.0:3456'
Starting docker backend     on 'https://manager.foobar.com' => 'http://0.0.0.0:3457'
Starting docker workers 

How

using docker-compose or (my favorite tool) crowdr. If we assume crowdr, a possible aap.json could look like this:

{
  "name": "foobar",
  "version": "1.0.0",
  "description": "",
  "website": "https://foobar.com",
  "repository": "https://github.com/jane-doe/small-sharp-tool",
  "logo": "https://small-sharp-tool.com/logo.svg",
  "scripts": {
    "postinstall": ["install_modules"]
    "postdeploy": ["start"],
    "start": ".crowdr/crowdr start",
    "stop": ".crowdr/crowdr stop",
    "build": ".crowdr/crowdr build",
    "backup": "zip -r data-`date +`.zip data",
    "test": "echo "Error: no test specified" && exit 0",
    "install_modules":"which npm && npm install; which composer && composer install"
  },
  "dependencies":{
    "crowdr:.crowdr":"git@github.com:polonskiy/crowdr.git",
    "docker.mysql:docker/mysql": "git@github.com:username/docker.mysql.git",
    "docker.mysql:docker/apache": "git@github.com:username/docker.apache.git"
  },
  "env": {
    "ADMIN_PASSWD": {
      "description": "A secret key for verifying the integrity of signed cookies.",
      "file": "data/.pw"
    },
    "WEB_CONCURRENCY": {
      "description": "The number of processes to run.",
      "value": "5"
    }
  },
  "devDependencies":{
  },
  "author": "",
  "license": "ISC"
}

With a crowdr .crowdr/config like this:

#!/bin/bash

HOST="$(tr -d '-' <<< $HOSTNAME)"
PREFIX="foo"

echo "
global project ${USER}_${HOST}_myproject

mysql build docker/mysql
mysql hostname $PREFIX-mysql
mysql volume $PWD/mysql-data:/var/lib/mysql

#comment

apache build docker/apache
apache hostname $PREFIX-apache
apache memory 5g
apache link mysql
apache volume $PWD:/var/www
apache env-file config.env
"
